STOP-COCK BOX.

SPECIFICATION forming part of Letters Patent No. 311,265, dated January 27, 1885.

Application filed March 3, 1834. (No model.)

ToratZZ whom it may concern.-

Be it known that I, BENJAMIN G. SMITH, of Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Stop-Cock Boxes, of which the following is a specification.

Stop-cock boxes have been made of cast-iron in the form of a tube through which the key or rod of the stop-cock passes, and at the bot- IO tom there is a space for the reception of the stop-cock. These stop cocks are usually placed in the pipe leading from the streetmain to the house or building, and are ernployed for cuttingoff the Water-supply. The

boxes are buried in the earth, and the upper end is usually level with the sidewalk.

Boxes constructed as aforesaid do not protect the stop-cock from the earth,which is liable to fill in th'e sides of the box where it is Besides this the stops that limit the movement of theplng of the cock are sometimes designedly misplaced, so that the cock is open when it appears to be closed.

My invention is made for removing the aforesaid objections; and it consists in Inova.` ble side plates for closing the fork at the lower end of the box, and in a check that is confined by a guide-ringin the upper part of the box, 3o so that the stops are always in the correct position in relation to the stop-cock.

In the drawings, Figure l is a vertical section of the box and elevation of the stop-cock. Fig. 2 is a detached side view of the lower end of the box. Fig. 3 is a section in larger size ofthe upper end of the box. Fig. 4 is a plan of the saine. Fig. 5 is a side and plan view of the guide-ring, and Fig. 6 is a side and plan view of the check.

The water or gas pipe a is provided with a stop-cock, b, and c is the rod or key that extends up to the surface 4of the ground. These parts are of usual character. Usually the rod c will be of square iron,with its lower end firmly secured into a socket in the upper part of the plug.

The box is composed of the cast-iron tube d, with forks e at the lower end, that straddle the pipe a, and there are feet f, that extend 5o out horizontally and serve to keep the box in place and prevent the frost lifting the same. The side plates, h, are made with openings that are ofa size to it the pipe c, and such plates are passed upon the pipe-one at each side of the cock-before the pipes and cock are connected up. After the forks have been placed over the pipe and cock the plates 7L are brought up at each side ot' the forks and the box raised or the pipe depressed, so that the plates slip in behind the lugs Z, and the 6o parts are iirinly connected together and the sides ofthe fork closed so as to exclude the earth, which is to be filled in around the box, as usual. Near the upper end of the tubular box and within the saine there are two inwardly-projecting lugs that form stops r to the projection s upon the check-piece o through a square hole in which the key or rod c passes. This check is made with a iiange or head that rests upon the top of the guide-ring a,-the 7c projection s being below the said ring, and there is a notch at 2 in this guidering which allows the projection s to be passed through "the same. The guide-ring u rests upon the stops r, and in order to hold the guide-ringin place I make a projection, fu, at one side to enter a recess in the interior surface of the, tubular box and insert a screw or screws, a, that pass through the tubular box into the edge ofthe guidering. The parts are made 8o so that the slot in the guide-ring a is above one of the stops r; hence the check o cannot be taken out after the part-s are placed together, and it is necessary to pass the projection o of the check through the guidering before the ring is put into the top of the box, and this has to be done before the box is applied to the key c, because such ring has to be entered at an inclination to insert the projection lu into its recess. In consequence of this con- 9o struction it is impossible to tamper with or change the check o without breaking some of the parts or taking up the box.

I claim as my inventionl. The combination,with the stop-cock and tubular box havinga fork and feet at the lower end, of the side plates, h, surrounding the tube a, or the tubular portion of the cock, and acting to close the sides of the fork, substantially as set forth.
